The purpose of the class is to keep a dynamic Array in it and dynamically retrieve the data type. For this, a generic class must be created.
Class features:
-
The default size of the array in the class is 10 and the number of elements of the array should increase by 2 times as needed.
-
The class must have two types of constructor methods
-
List() : If the empty constructor is used, the initial size of the array should be 10.
-
List(int capacity) : The initial value of the array should be taken from the capacity parameter.
-
size() : Returns the number of elements in the array.
-
getCapacity() : returns the capacity of the array.
-
add(T data) : It should be used to add an element to the array of the class. If there is not enough space in the array, the array size should be doubled.
-
get(int index): returns the value at the given index. Returns null if invalid index is entered.
-
remove(int index): should delete the data in the given index and shift the data after the deleted index to the left. Returns null if invalid index is entered.
-
set(int index, T data) : It should replace the data in the given index with a new one. Returns null if invalid index is entered.
-
String toString() : A method that lists the elements in the array of the class.
-
int indexOf(T data) : Returns the index of the object given in the parameter in the list. Returns -1 if the object is not in the list.
-
int lastIndexOf(T data) : It tells the last index of the specified item in the list. Returns -1 if the object is not in the list.
-
boolean isEmpty() : Indicates whether the list is empty.
-
T[] toArray() : Converts the items in the list into an array in the same order.
-
clear() : Deletes all items in the list, making it an empty list.
-
List sublist(int start,int finish) : Returns a list of the index range given in the parameter.
-
boolean contains(T data) : It tells whether the value given in the parameter is in the array.
